Problem description

A buffer overflow in the SGI image format decoding routines used by the
CUPS image converting filter imagetops was discovered. An attacker
could create malicious SGI image files that could possibly execute
arbitrary code if the file was printed (CVE-2008-3639).

An integer overflow flaw leading to a heap buffer overflow was found
in the Text-to-PostScript texttops filter. An attacker could create
a malicious text file that could possibly execute arbitrary code if
the file was printed (CVE-2008-3640).

Finally, an insufficient buffer bounds checking flaw was found in
the HP-GL/2-to-PostScript hpgltops filter. An attacker could create
a malicious HP-GL/2 file that could possibly execute arbitrary code
if the file was printed (CVE-2008-3641).

The updated packages have been patched to prevent this issue; for
Mandriva Linux 2009.0 the latest CUPS version (1.3.9) is provided
that corrects these issues and also provides other bug fixes.
